To check whether a specific part of your organization is underutilizing RingCentral products, you can use By Department or By Site to further understand the departments that have adopted RingCentral optimally and the ones that need your focus.
The most active departments have users who have better realized the value of the product and can be useful in establishing and educating the rest of your organization on best practices. The departments or sites that are underutilizing the products may need training in accessing or using the product and features in the best possible way as it applies to their roles.
To determine if any recent event triggered a drop in usage, you can use calendar widget presets to go back in time and understand the change in active users. You can also study the trend of active users at a more granular level on the Active User Trend graph
